Bug in itemize
by David Arnold 13 Jul '07

13 Jul '07

All, Think I found a bug in itemize. \starttext \startitemize[a,columns,three] \item $|x|>-5$ \item $|x|>0$ \item $|x|>4$ \stopitemize \stoptext On my system, the first item is not labeled, the second and third are labeled "a" and "b." gimp $ ctxtools --contextversion CtxTools | context version: 2007.06.06 09:53 (/usr/local/gwTeX/ texmf.local/tex/context/base/context.tex) CtxTools | context version: 2007.06.06 09:53 (/usr/local/gwTeX/ texmf.local/tex/context/base/cont-new.tex) Any ideas?

\definestartstop with arguments
by Vyatcheslav Yatskovsky 13 Jul '07

13 Jul '07

Hello, Pleeease, I need a help. I might formulate my previous question badly, so let me restate it. How to handle optional arguments (one or two) with \definestartstop? More specifically, how to replace hard-coded "Logging-On" string so that I could write \startusecase[Logging-Out] Bla-bla \stopusecase or even \startusecase[Reminding password][User should be already logged on] % where the last argument is completely optional and is shown on an additional line % with "prerequisite" mark Bla-bla-bla \stopusecase My current startstop definition is \definestartstop[usecase][before={\starttextrule{Use Case: Logging-On}\startpacked\startmypar{\bf User Intentions}\mypar{\bf System Responsibilities}\stopmypar}, after={\stoppacked\stoptextrule}] Best, Vyatcheslav

Hello, I want to convert my following code into a custom \start \stop pair. \starttextrule{Use Case: Logging-On}\startpacked Text.... \stoppacked\stoptextrule It seems to me that using \definestartstop[usecase][...] command is the most approprate, but I cannot get how to achieve different captions: \startusecase[Logging-On] Text... \stopusecase \startusecase[Reminding Password] Text... \stopusecase Best, Vaytcheslav Yatskovsky

The result is bizarre both in xpdf and in evince (there is no acroread for powerpc, shame on adobe!). But this seems to be merely an error in the viewer; I have often found the linux pdf viewers to be extremely inferior to what I get in OS X; one of the reasons why I will not be able to switch to linux anytime soom.

PNG output
by w.neimeijer＠hccnet.nl 12 Jul '07

I want to convert my standalone formulas to PNG to display these formulas on my website. What I am doing is the following \starttext \startTEXpage \startformula e^{i x} = \cos x + i \sin x \stopformula \stopTEXpage \stoptext and process this via texexec --pdf to get a PDF file. I tried to convert the resulting PDF file via gswin32c to png but the resulting PNG output is not so good. Then I read dvipng could do the job, which means I have to produce dvi output via texexec --dvi but than I get complaints from dvips that it cannot find the file tex.pro for the specials. However a png file is produced. Help appreciated TIA Wim

frames in ConTeXt and metafun
by Thomas A. Schmitz 12 Jul '07

12 Jul '07

This is a very small cosmetic problem, but it bugs me: I'm preparing a background for a presentation, and I want a frame with a transparent color to appear on every slide, so I define an overlay and use metapost. I also want to frame some text elements, so I use a \framed. The problem is that in the \framed, the lines of the frame overlap at the edges, so with a transparent color, the corners are slightly darker. The minimal example below shows the problem. Any solution? Is it possible to have the frame around \framed drawn by metapost? Thanks! Thomas %%%%% MINIMAL EXAMPLE %%%%%% \setupcolors[state=start] \definecolor [MyFrameColor] [b=.55, t=.5, a=1] \starttext \startuseMPgraphic{fancyframe} draw unitsquare xyscaled(8cm,8cm) withpen pencircle scaled 4pt withcolor \MPcolor{MyFrameColor} ; \stopuseMPgraphic \useMPgraphic{fancyframe} \framed [rulethickness=4pt,framecolor=MyFrameColor,height=8cm,width=8cm]{\strut} \stoptext

Enumerations and numbered labels
by Norbert Zeh 12 Jul '07

12 Jul '07

Hi folks, I've recently started to consider ConTeXt as an alternative to my long-time friend LaTeX. I like ConTeXt very much but noticed a few things that are either less than ideal or maybe I simply haven't figured out yet how to do them right. Here are the first two: 1) Enumerations I've read in a few places that this is what is to be used whenever I would use theorem-style environments in latex. There are two things I seem to be unable to do: Creating Theorems that look like this. --------------------- THEOREM 1 It would be nice if Context could produce a theorem where the title is not separated from the text and the next line has no hanging indent. --------------------- I was able to produce only ---------------------- THEOREM 1 It would be nice ... ---------------------- or ---------------------- THEOREM 1 It would be nice ... ---------------------- using location=top or location=hanging. What I want is no hanging indent at all. (I also tried location=serried, which produced an overly large gap between THEOREM 1 and the theorem text. The second thing I am used to in latex is the option to place things in parentheses by providing an optional argument to the environment. E.g., in assignments I typeset, I often have either \begin{question} ... \end{question} which simply produces -------------------- Question 1 ... -------------------- or \begin{question}[20 marks] ... \end{question} which produces -------------------- Question 1 (20 marks) ... -------------------- This second option is easy to simulate if I can produce something that has no hanging indents. As it is, I can't. 2) Numbered labels I tried to use numbered labels plus a little bit of tex-code to simulate the above environment. The gist is that I used \definelabel[question][location=intext,text=Question] to define the label and, wherever I needed a new question, \question [ref]. The result of writing \question[ref], however, was "Question Question 1". The label always seemed to be duplicated for some reason. Is this a known bug? Thanks for your help with this.

Hi all, Can someone please have a look at this for me? I have to run off for TUG2007 now (ye, already), and I could not discover what is wrong. The problem seems to be with false positives from \doifcurrentlevelelse, but that is the only thing I could discover til now.

Here is a directory which should work out of the box; test file is bib-test.tex. I think I found the key to the problem: For \title, the entry of the previous \title is repeated. For \chapter it behaves correctly. I define my articles in terms of \title, and each article is within a \start-stopproduct file. So basically the bib-module needs to support \title as well (used to do so).
